The most impressive drier I ever saw was in a bar in Dresden. It was called the 'AirWolf' and my (German) friend remarked that it appeared to be based on Rommel's desert air-conditioning system.
Conventional hot-air dryers actually work and work quickly in Alberta. Something to do with the altitude, I've been told. After a few dryings your hands are like lizard skin though.
[Rosie] If not pouffed then what is the verb for the application of a powder to a surface (or into a crack or hole - oh dear, this just gets worse) by air-propulsion, generated by squeezing a slightly flexible plastic bottle? And I tried the boiling water first too :o( [Chalks] I bought Homebase's own brand, about £3 - very happy. Ant free.
